on mine (this is gonna shock you) the regulation load is 144 gr of either pyrodex or ffg (i use pyrodex)with either a 275 gr round ball or the 330 gr lee REAL conical. this doesn't mean that its your load though. My kodiak is serial 3XX and was one of the first brought into country, thus was regulated (to a point). latter rifles were not regulated and came with 2 rear sights so you could sight each barrel with its own sight. To scope the thing I would think you would have to use a very long eye relief scope so that the powder blast from the fences wouldn't coat the rear lens.
